An efficient selenium-catalyzed direct oxidation of benzylpyridines in aqueous DMSO has been successfully developed by using molecular oxygen as the oxidant. A variety of benzoylpyridines with broad functional group tolerance were obtained in modest to excellent yields and with exclusive chemoselectivity. (Figure presented.).

The synthesis of the 2-furyl ketones 5-7 and 13 and their reaction with ammonium acetate in boiling acetic acid to 3-substituted 2,2'-bipyridines and to 2-(2-pyrimidinyl)-3-pyridinol (14) via a ring-transformation reaction are described.Strong intramolecular hydrogen bonds are responsible for their physical and chemical properties.
